  • the hollow profile 24 projects into the groove 3, when the band part is in the mounting position O.
  • the clamping screw 10 has a screw head 27 which rests on a support surface 28 of the hinge part 21 and the distance U between the support surface 28 and the abutment 11 is smaller than the distance V between the support surface 28 and the support surface 6a, when the band member is in mounting position O.
  • Figures 20 and 21 show the clamping element 8 pivoted in its mounting position H.
  • Figures 22 and 23 show the clamping element, as it rests with a portion of its extension 9 on the support surface 6a of the profile 2.
  • FIGS. 24 and 25 show the clamping element 8 with toothing engaged in the holding surface 6a.
  • the extension of the projections 9 and / or the position of the clamping screw holes 38, 39 in the band part and thus the distance K of the clamping elements perpendicular to the longitudinal direction L of the profile are chosen so that the band member 21 is perpendicular to the plane E of the slot opening displaced so that the clamping elements 8 with their extensions 9 can be introduced into the groove 3-if no regions of the extensions 9 are directed outward-and clamping forces can be transmitted to the profile 2 via the clamping elements 8 -when regions of the extensions 9 are directed outwards.
  • Approx. Fig. 23 shows an O-ring 36 made of plastic, to effect a frictional connection between the clamping screw 10 and the band part, which is passed through by the clamping screw 10 and is arranged in an annular groove of the band part.
  • FIG. 5 shows that by a rotational actuation of the respective clamping screw 10, the respective clamping element 8 by frictional engagement of the thread of the clamping screw 10 with the Tapped hole 18 from the mounting position M in the mounting position H is rotatable.
  • the axis of rotation D of the clamping elements 8 coincides with the axis A of the clamping screws 10.
  • Fig. 5 shows that the clamping elements 8 leaves a distance G to the adjacent undercuts 5 in the mounting position when the band part 21 is displaced in the assembly position O, so that the assembly movement B is not obstructed.
  • Figures 2 and 4 show that the profile 2 has two projections 13, 13 ⁇ and the band member 21 has two grooves 14, 14 ⁇ and both projections 13, 13 ⁇ in mounting position O of the band member 21 each in a groove 14, 14 ⁇ of the band part 21 engage. It can also be seen that in each case a projection 30, 30 'of the band part 21 is arranged on the side of the groove base of these grooves 14, 14 ' . This projection 30, 30 ' has outer walls which run towards each other at an acute angle in the direction of the assembly movement B. These projections 30, 30 ' are in turn arranged in lateral grooves 19, 19 ' of the profile when the band part is in the mounting position O.
  • the abutment surface 7a on the profile 2 and the rotation abutment surface 20 on the band part 21 prevent the clamping elements 8 from being rotatable more than 90 °.
  • Figure 21 shows the situation in which the clamping elements 8 are rotated by turning the clamping screws 10 in the mounting position H, but the clamping screws 10 are not yet tightened.
  • the clamping element moves in the axial direction D of the clamping screws, whereby the teeth 37 of the clamping elements 8 for the first time come to rest on the profile 2 (shown in Fig. 23).
  • the clamping elements 8 move even further in the axial direction A of the screws.
  • the clamping elements 8 then come for the first time on the band part 21 to the plant. As a result, tilting of the clamping elements 8 is prevented.
  • the teeth 37 dig into the profile 2.
